    Researchers are producing an unprecedented deluge of data by using new methods and instrumentation. Others may wish to mine these data for new discoveries and innovations. However, research data are not readily available as sharing is common in only a few fields such as astronomy and genomics.Data sharing practices in other fields vary widely. Moreover,research data take many forms, are handled in many ways, using many approaches, and often are difficult to interpret once removed from their initial context. Data sharing is thus a conundrum. Four rationales for sharing data are examined, drawing examples from the sciences, social sciences, and humanities: (1) to reproduce or to verify research, (2) to make results of publicly funded research available to the public, (3) to enable others to ask new questions of extant data, and (4) to advance the state of research and innovation. These rationales differ by the arguments for sharing, by beneficiaries, and by the motivations and incentives of the many stakeholders involved. The challenges are to understand which data might be shared, by whom, with whom, under what conditions, why, and to what effects. Answers will inform data policy and practice.

    In the process of feature selection, term’s weight determines whether the term can be a feature. But the weight is affected by many factors, the main factors are term’s importance, characteristics and representative. With the consideration of those factors, a new function TW (Term Weight) based on the importance of the feature and the ability of category distinguishing, is brought to be an improved method to select features. After that, experiments on the comparison between term’s CHI, IG and TW validate that TW can increase the weight of special features in a class and can decrease the weight of unimportant features. Finally, the validity of the new algorithm in feature selection is proved by the classification experiments on Chinese classification corpus by three classifiers.

    Synonym of terminology is a basic type of relationships between terms. Based on the English-Chinese alignment dictionary, this paper proposes recommended method of term synonyms, deriving of Chinese and English translation in pairs, and optimizes synonyms results by weighted optimization measure. The experiments indicate that both the accuracy and efficiency of synonym recognition are improved by the method, which is beneficial to the construction of knowledge organization systems, encyclopedias and information retrieval.

    The recognition of the characteristics of users’ personalized interests can be enhanced by utilizing of the information in the users’ accessing time. This paper proposes a method of constructing readers’ personalized profiles with the timing information of readers’ borrowing records in book recommendation service of library. This paper begins with the introduction of three extended time indexes based on the analysis of the characteristics of readers’ borrowing time, meantime, it also discusses the recognition of the degree of readers’ interests, and the visualization of timing evolution trend of readers’ interests. Finally, some related experiments that show the performance improvements are reported.

    The paper, taking advantages of cloud model in expressing uncertainty of fuzziness and randomness in nature, proposes that there are uncertainties in cloud model and readers’ multi-featured books preference.The paper computes the weighted similarity of readers’ majors, genders and grades,uses the backward cloud algorithm to compute readers’ preference of borrow-return time interval that is expressed in cloud expectation, entropy and hyper entropy,and then computes the readers’ cloud similarity. Combining multi-featured similarity of readers with cloud similarity,the paper finally recommends books to readers with copied ones and proves the validity of the algorithm by experiments.

    Taking the research field about “complex network” during 1975 and 2012 as an example, this article explains the characteristics of network evolution and knowledge transmission from static characteristics, topological characteristics and dynamic evolution characteristics of the four developing stages of scientific collaboration network. The simulation results demonstrate that the speed of the dissemination of knowledge is influenced by individual innovation ability obviously when knowledge transmission rate is constant and that the speed of the dissemination of knowledge is influenced by the knowledge transmission rate slightly when individual innovation capability is constant.

    Based on the network collective behavior on micro-blog public opinion, laws and perception of implementation intentions have become a hotspot for early warning and public opinion research. Therefore, the purpose of this study through three online micro-blog experiments is to explore the laws of collective behavior on micro-blog public opinion from the topic heat and trend, emotional heat, social semantic networks and micro-blog influence. The results indicate that firstly implementation intentions of the micro-blog collective behavior are affected by the topic heat and trend, emotional heat, network centrality, the number of fans, number of attention and original; secondly implementation intention of value-orient, safe-orient and control-orient exhibited significant are differences in topic trend, emotion changes, micro-blog influence, social semantic networks etc. Therefore, the results of the experimental study have certain implications to make guide strategy for micro-blog hot events, and it may provide practical guidelines for strengthening social management and crisis response.

    The administrator of library’s microblog cannot guarantee the 24-hour management. Based on Sina microblog, this paper designs an assisted tool which can timely post messages extracted from information libraries and can reply to the questions by extracting answers from knowledge bases, by ways of reading web documents, segmenting Chinese words and operating PC client of Sina microblog. The application example shows that the program can help managing microblog, especially when the administrator is offline.
